Abstract
A method for 360 video data processing based on multiple viewpoints performed by a 360 video receiving apparatus according to the present invention comprises the steps of: acquiring, from received video signals, image information for pictures of multiple viewpoints-based 360 videos and metadata for the multiple viewpoints-based 360 videos, wherein the metadata includes multiple viewpoint information; decoding an image of a first viewport of a first viewpoint on the basis of the metadata and the image information; rendering the image of the first viewport into a 3D space; decoding an image of a second viewport of a second viewpoint on the basis of the metadata and the image information; deriving, in a case in which the hotspot in the first viewport is selected, the second viewport in the second viewpoint connected through a hotspot on the basis of the multiple viewpoint information; and rendering the image of the second viewport into the 3D space.
